Measuring great saphenous vein (GSV) diameter is standard in pre-interventional assessment of varicose disorders, but has never been properly validated. This work assessed the relative value of measuring GSV diameter at the most often used sites: the sapheno-femoral junction and the proximal thigh.
All superficial tributary veins should discharge into the GSV between the terminal and preterminal valve. Thus, the exact position and the frequency of both the venous valves in the GSV and at least the major superficial tributary veins (MSTVs) gain in importance.
